+ regen Ada html documentation. + change order of -I options from ncurses*-config script when the --disable-overwrite option was used, so that the subdirectory include is listed first. + modify the make-tar.sh scripts to add a MANIFEST and NEWS file. + modify configure script to provide value for HTML_DIR in Ada95/gen/Makefile.in, which depends on whether the Ada95 binding is distributed separately (report by Nicolas Boulenguez). + modify configure script to add -g and/or -O3 to ADAFLAGS if the CFLAGS for the build has these options. + amend change from 20070324, to not add 1 to the result of getmaxx and getmaxy in the Ada binding (report by Nicolas Boulenguez for thread in comp.lang.ada). + build-fix Ada95/samples for gnat 4.5 + spelling fixes for Ada95/samples/explain.txt > fixes for Ada95 binding (Nicolas Boulenguez): + add item in Trace_Attribute_Set corresponding to TRACE_ATTRS. + add workaround for binding to set_field_type(), which uses varargs. The original binding from 990220 relied on the prevalent implementation of varargs which did not support or need va_copy(). + add dependency on gen/Makefile.in needed for *-panels.ads + add Library_Options to library.gpr + add Languages to library.gpr, for gprbuild
